My travel times are referanced to a heavly loaded truck, so you may drop 30 to 45 mins off of the times. Also you didn't specify your route, so I will use the way I would go. Co. Sprs. to Chama 117 to Penrose to Poncha Jct. (50) 285 to Villa Grove 17 to Alamosa, 285 to antonito 17 to Chama. My time 3 to 4 hrs. Chama to Durango take 84 to Pagosa Sprs. 160 to Durango 2hrs.+ Durango to Gunnison to Co. Sps. this one is tough because there are many differant ways to go. I would allow a full day for this one. might consider over nite in Gunnison.....keith
